ADVERTISN G SIGN.

Application led March 11, 1924. Serial No. 698,515.

the type adapted to be mounted under a` transverse supporting plane of an aircraft, and the principal obyect is to provide light and simple, yet strong and 'durable support- 111g means adapted for direct connection to,

the rigid struts, which rise from the lower plane of every aircraft embodying upper and lower planes.l

With th foregoing in view, the invention resides in the novel subject matter hereinand of the plane.

after described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a vertical sectional view through the lower plane of an aircraft, show-V ing the improved sign-supporting means attached to the usual struts and also attached to the'main'spars.

Figure 2 is a horizontal sectional view aS indicated by line 2-2 of Fig. 1.

Figur dicated by line 3--3 of Fig. 1.

In' the drawings above briefly described, the numeral 1 designates what may be considered as the lower plane of a biplane, `said plane having the usual main spars 2 from which the struts 3 rise to the plane above, said struts being shown in inwardly spaced relation with the front Aand rear tip-rails 4 To be supported under the plane 1, is a sign consisting of a plurality of letters 6, in the present disclosure, these letters .being preferably of inverted channel shape as shown in Fig. 3, so that electric lights'? may be placed within the channels to illuminate the sign atnight. The letters 6 are shown detachably and adjustably connected b bolts 8 with front'and rear bars 9 whic extend under the tip-rails 4 and 5 and are preferably of the angle shape shown, in transverse section. Metal hangers 10 are e 3 is a vertical sectional view as in-` shown secured at their lower ends to the bars 9, by bolts or the like 11, the upper ends of these hangers being adapted for connec-v tion with the struts 3, for which purpose l have shown them provided with contractible collars 12 having clamping bolts 13. When the struts 3 are 1n inwardly spaced relation with the front and rear edges of the plane 1,'the upper portions of the hangers l0 exltend in substantially horizontal directions as indicated atv 14, to extend o'ver the portions of the plane between said struts and edges. As these portions are usually rather rigid, the portions 14 of the hangers may well contact `directly therewith, as shown in Fig. 1.

As the letters 6 are of very light construction, it is advisable to provide some means to support the intermediate portions thereof. For this purpose, l have shown'them secured adjustablyv and removably by bolts 8 lto additional bars 9a parallel with the bars 9, said bars 9El being' supported by hangers 10a whose upper ends are secured to the struts 2 in any desired manner, for instance by bending the ends of the hangers laterally as shown and passing attaching bolts 15 therethrough atopposite sides of the spars,

suitable plates or the like 16 being extended across the top of the plane 1, over the spars, to engage said bolts.

vBy providing the construction shown and described or a substantialV equivalent thereof, l

the sign will be eiectively supported, without any danger whateverV of injuring any parts of the aircraft.

As excellent results may be obtained from the details disclosed, they are preferably followed, but within thescope of the invention as claimed, numerous minor changes may be made.

I claim:

1. rlhe combination with an aircraft having a transverse supporting plane, and struts risin porting a ysignunder said plane, including angers secured to said struts.

2. The combination with an aircraft having a transverse supporting plane, and Struts "rising therefrom in inwardly spaced relation with the front and rear edges thereof of means for supporting a sign under sai plane, including hangers secured tosaid struts, extending therefrom over the upper side of the plane to the front and rear e therefrom, of means vfor suplos - ers extending from said 4collars over vthe upper side of thegplane tothe edges of the latter, and extending downwardly across said edges. t l

5. An attachment for an aircraft having a plane and struts rising therefrom in inwardly spaced relation with its edges, said attachment comprising a sign for disposition under the piane, and sign-supporting means includinghangers adapted for connection to the lower ends ofthe struts, saidy hangers extending substantially vhorizon- 'tally'from' their .attaching means to extend over portionsof the plane and thenl extending downwardly to pass across the edges of the piane.

. v6. An attachment for an aircraft having struts rising from a piane, said attachment comprising a sign for disposition under the plane, and si -sup rting means having sustaining co ars a apted to be clamped around the struts.

around t e struts, yand hangers connec "1. An lattachment for an aircraft having struts'risingfrom a piane, said attachment comprisin a-sign for disposition under the plane, an @IgA-supporting means having susta' co ars a' apted to be clam ed to said collars and extending substantially horizontally therefrom to extend over portions i of the piane, said hangershaving portions asesinas horizontalportions to extend across plane, and supporting means for said sign 'including a hanger having extended bearing on the upper side of said plane and extending across amain frame member there-- of, said hanger having a portion extending across an edge of the plane.

9. The combination'with yan aircraft having a skeleton framework, and a supporting plane; of a sign under said plane, and supporting means for said sign including hangers extending across 'the front and rear` edges of said plane and extending inwardly over the front and rear portions of said plane, and means securing the upper ends of said hangers to rigid parts ofsaid skeleton framework.

l0. An attachment for an aircraft having a supportingplane, comprising a sign for disposition under the plane, and sup rting means for s 'said sign including lili) adapted to extend verticllyacross lthe front and rear edges of the plane, said hangers having inturned upper ends to rest on the frontend rear edge portions of the plane, saidl inturned portions. bein securing .to frame parts of t e craft.

11. An attachment for an aircraft having a supporting plane, comprising a sign for disposition under the plane, and supporting means hanger having a vertical portion to extend across an edge of the plane, and a substanjtially horizontal portion adapted to extend over and have extended contact with the upr side of the lane.`
